Answer 1

Rough Code which will help you:

PhoneArguments arguments = new PhoneArguments(PhoneArguments.ARG_CALL, "dial num.")    
ButtonField buttonField = new ButtonField("Dial",ButtonField.CONSUME_CLICK)
        {
            protected boolean navigationClick(int status, int time) 
            {
                Invoke.invokeApplication(Invoke.APP_TYPE_PHONE, arguments);
                return true;
            }
        };

I hope it will helpful to you.
